Pex 1/2" T joint

I decided to clean up my garage door wires and put them in 1/2" Pex Tubing. I wanted a joint for my 2nd door to join in the same channel and, well there wasn't a joint that i could find to work so i decided to make my own. Its a snug fit, definitely don't need to glue it in place. Probably not the best idea to use this for water as i made it with the intention on hiding wires and theres no gaskets etc. Just figured i would share.

The walls on the ends are 1.5mm thick, and then the core of it is 3mm thick. With the clearances, this stops your tubing 15mm into this joint.

The outer diameter of the pex 1/2" pex is 15.8mm, so there is .2mm of clearance. it makes this snug but not loose enough for the tubes to fall out while still being easy to twist into place.
